Systems and methods for collecting fluid from a subject

A method of receiving bodily fluid from a subject, comprising:

• placing a device for receiving bodily fluid from a subject on skin of the subject, the device including a fluid transporter comprising a base and at least one inner surface, the base and the at least one inner surface at least partially defining a recess, the recess having an opening defined by the base, and the device including a flow activator;
• actuating the flow activator to pierce the skin and cause release of bodily fluid from the subject;
• and
• creating a vacuum from a vacuum source to draw the bodily fluid from the subject through the opening into the recess and into a storage chamber via a channel fluidly connecting the storage chamber and the recess,
• wherein a first wall and a second wall protruding from the at least one inner surface into the recess guide the bodily fluid from the opening toward the storage chamber,
• wherein the first wall and second wall flank a longitudinal axis of the channel,
• wherein the first wall and the second wall are distinct from the base.
